` To atl whom it may cancern:

Be it known that we, Enron T. CHRISTEN- snN and DAVID M. TULLOOH, both citizens of the United States, and residents of the city fullyappliedfto such'pipeswhen arranged under the Conditions required.- Such condi- "tions and disadvantages are overcome by the means illustrated in the accompanying draw- 5 of N ew York, borough of Manhattan, in the ings, in which drawings like characters of ref- 6 county-and State of New York, have inventerence indicate like partsf throughout the ed a new and Improved Pipe-Coupling, of I`views, and in whichwhich the following is a full, clear, and exact Figure 1 is a sideffelevation of a pipe-cou escription. lino' embodying our invention app ied tot e 1o Our invention relates to pipe-couplings ends of two adJacent pipe-sections Fig.2is v65 adapted to be used on pipes of lar e diama vertical v'transverse section of a coupling eter, and has for its object to pro'vi e means. l embodyin our invention, showing the secfor repairing and cou lin the broken sectionsjarran'ged at an'angle to eachother; and tionso large pi es w en ocated under wa' Fig. 3 isa verticallcross-section taken on the ter, and especlally when lying on the bed cfa line 3 3 of Fig'. 2. 7 river, and to adapt such coupli' and the As illustrated'in the drawings, the main pipe-sections connected therewit to conortion ofthe coupling consists of two simiform to the contour of the ground on which 'ar .cylindrical sleeves ,,1,'havingffanges 2 the pipes lie. formed on their adjacent ends', extending in a 20 The connecting ends of large pipes lyin on plane inclined' to theffaxial line'fofthe sections 7 5 the bed of a river frequently become bro en 1.

1. A pipe-coupling comprising similar eylindrieal sleeves having llaring outer ends, and provided on their adjacent` inner ends with ilangeseXt-ending in a plane inclined to the axial line of said sleeves, each flange being provided with a series of apertures evenly disposed lroin each other, and adapted to register with the apertures ol the adjacent flange, bolts engaging said apertures and clamping said y'lai'iges together, set-rings holted to the outer ends oli said sleeves independently ol" each other, and provided with an inner diameter extending flush with the inner diameter .of the respective sleeves, substantially as shown 'and deseriliei'l.

2. A pipe-coupling comprising similar cvlindrical sleeves having'lilaring outer ends, and provided on their adjacent inner cnds with flanges extending in a plane inclined to the axial line of said sleeves, cach llangc being provided with a series olE apertures evenlv disposed troni each other and adapted to .register with the ajiertures ol the adjacent llange, holtsengaging said apertures and elamping said llangcs together, rings bolted to the outer ends ol' said sleeves independently ol eachother and having their inner Wall extending llnshwith the inner wall of said sleeves, and constructed in sections adapted to be adjusted laterally relatively to each other, i'i'ieans l'or elainping the sections of said. rings together7 and lor securing said ring lto the end ol the inljacent. sleeve, substantially as shown and described.

3. A jupe-coupling coinprising siniilar cylindricalreves having llaring outer ends, and provided on their adjacent inner ends with flanges'extending in a plano inclined to the axial line ol said sleeves, each 'ilangc being provided with a series ol apertures evenly disposed iroui each other and adapted to register with the apertures oi" thc adjacent llange, bolts engaging said. apertures and clamping said llanges together, set-rings provided with a beveled. inner end adapted to telescope with the llaring end ol the adjacent sleeve, and with their walls exlendii'ig llush with the inner walls ol' their adjacent sleeves,
